Productive Collaboration

Ingredient disclosure is an undertaking with real challenges, requir ing significant work. Our efforts have involved diligent collaboration between Stego’s Technical and Sustainability teams, along with our upstream suppliers. Getting to this point has included navigating sensitive trade secrets and proprietary information across our supply chain. These challenges are not unique to Stego, as many building product manufacturers face similar obstacles to provide continued and more robust transparency. Yet, in the challenge, also lies oppor tunity to:

Reinforce the importance of ingredient and product disclosure information to upstream suppliers.

While we believe Stego holds a unique position as an industry leader in material transparency — partic ularly outpacing the transparency offered by other options in the below-slab vapor barrier market — we acknowledge there is also room for our continued improvement and optimization. We feel our current efforts demonstrate a clear understanding and commitment to a better, healthier built environment. How to Find Transparency Reporting Information: Published HPDs, Red List Free letters, and VOC Emis sion certification documentation are accessible on our website or from your local Stego representative. Stego products and transparency documentation is also easily accessible on healthy product databases, like the mindful MATERIALS Portal.
